Manufactured under one or more of the following U.S. patents:
3,817,279: 3,817,286; 3,817,489; 3,820,171,754; and
4,233,698. Also covered by various foreign patents (country
and number available upon request) and other patents pending.
The Sloan F L U S H M ATE®Flushometer - Tank System provides the highest
p e rf o r mance capability available today in the ULF (Ultra-Low Fixture) category. That
means it consumes less than 1.6 gallons/6 liters of water per flush. It achieves this
remarkable perf o rmance by using compressed air inside the tank, which creates a
t u r b o - c h a rg e d flushing action for effective bowl cleaning. Compared to other types of
low consumption water closets, F L U S H M AT E offers many distinct advantages.
(F)
WA R N I N G : When servicing or replacing components to the F L U S H M AT E F l u s h o m e t e r- Ta n k
System, make certain that the water supply is turned O F F and the toilet is then flushed to
relieve pre s s u re in the vessel.
N E V E R use lubricants on any of the components unless otherwise noted in this manual.
N E V E R use corrosive chemicals or household cleaners on F L U S H M AT E p ro d u c t s .
INSTALLATION _______________________________________________________________________________
The Sloan FLUSHMATE ®Flushometer -Tank System Fixture installs in the same manner as other water closets. Please follow
the instructions provided by the fixture manufacturer.
Using the gasket, washer and nuts provided with the fixture, assemble the tank to the bowl. Before connecting the supply to
the tank, be sure the supply line is flushed clean. Do this by running water from the supply stop into a bucket until water
flows clear.
After connecting the supply line to the tank, turn on the water again and check for leaks. You may be required to make
adjustments to the actuator for either pushbutton type or trip lever type units. Please follow the instructions provided by the
fixture manufacturer.
TROUBLESHOOTING __________________________________________________________________________
CONDITION: Water runs on and will not shut off.
A newly installed toilet that does not shut off may be caused by inadequate or low pre s s u r e, and is usually the result of an insuff i c i e n t
water supply flow rate into the FLUSHMATE Vessel. (NOTE: The recommended static pre s s u re range by code is 20 P.S.I. to 125 P. S . I . ) .
If sufficient supply pre s s u re has been verified and the toilet continues to run, the following steps may be re q u i re d :
Step 1. Make sure supply stop is fully open.
Step 2. Check the Supply Shank Screen for any obstruction that would
restrict the supply.
Step 3. Check the Actuator adjustment (see Installation Procedure). The
linkage rod or push button should not interfere with the flush.
On Pushbutton type units, loosen the setscrew on the actuator
(See Number 4F on the component list) and rotate the Actuator
up or down until proper clearance is obtained (1/8”). For trip
lever units, gently lift the actuator rod and observe proper
clearance is maintained (approximately 1/8” gap between rod
and actuator) See Figure 1.
Step 4. Check the Flush Valve Cartridge Assembly for proper
installation. Proceed as follows:
a) Turn off the water supply and flush the toilet.
b) Remove the Flush Valve Cartridge Assembly using pliers’
handles as shown in Figure 2. NOTE: You may be required to
disconnect the Actuator Linkage Rod to remove the Flush
Valve Cartridge Assembly.
c) Inspect the “O” Rings on the Flush Valve Cartridge and the
seating area inside the tank for wear and/or improper seating.
Step 5. Reinstall the Flush Valve Cartridge Assembly.
First, insert the cartridge into vessel and, while gently pushing
down on the cartridge, turn the cartridge counter-clockwise
until you hear an audible click, indicating that the threads are
now aligned. Screw cartridge clockwise into place until two
black threads of the vessel are showing. Next, turn on the water
and continue to turn cartridge until the water stops running. Do
not over-tighten.
FIGURE 1
FIGURE 2
Step 6. If the Tank continues to run-on, push down lightly on the Flush Valve Actuator. If the water stops running, it is an
indication that the Flush Valve Cartridge requires tightening (clockwise). If water still runs on while pushing down on the
actuator, the Flush Valve Cartridge requires loosening (counter-clockwise).
NOTE: Adjust the Flush Valve Cartridge Assembly in quarter to half turn increments until the water stops running. Always turn
the water supply off for all adjustments. Flush Valve Cartridge turns the water off.
Step 7. If replacement of the Flush Valve Cartridge is necessary, follow the instructions in Step 5.
CONDITION: Weak or Sluggish Flush.
Step 1. Check the water pressure (20psi - 125 psi recommended). If OK,
then check the Flush System by removing the tank Cover and tripping
the Actuator. While the unit is flushing, gently raise the Actuator. Water
should flow freely and wash away any debris in the supply line and
Vessel.
Step 2. Check the Air Inducer for sufficient air draw. The Air Inducer is
designed to draw air during the refill cycle. To test the Air Inducer, place
a small amount of water (2 to 3 drops) in the orifice of the Air Inducer
cap and flush the toilet. If the Air Inducer is functioning properly the
water will be drawn in. If not, it will need to be cleaned and tested again.
TO CLEAN AIR INDUCER: (Figures 3 & 4)
a) Turn off the water supply and trip the Actuator.
b) Unscrew the Air Inducer Cap, clean thoroughly and remove
any obstructions. Reassemble. (Hand-tighten ONLY.)
c) Turn on water supply. Wait for the Vessel to refill (30 to 60
seconds.) Repeat Step 2 above. If the Air Inducer does not
function properly, replace the Upper Supply Assembly.
Step 3. Check the Flush Valve Cartridge for leaks. Turn the water supply
off and drain the vessel by tripping the Actuator and holding it down
until completely drained. Next, pour a cup of water onto the Cartridge
Housing area as shown in Figure 5. Turn on the water supply. If a leak is
detected (a steady flow of bubbles from the center of the Cartridge
Area), the Cartridge should be replaced.
Step 4. Check Lower Supply. Turn the water off and relieve the Vessel
pressure by flushing the toilet. Remove the supply line connection to the
shank. Remove any obstruction in the supply shank screen. If
necessary, you can use a small brush to gently brush the screen.
Reattach the supply line to the supply shank and observe connections to
assure no leakage. IMPORTANT: If you are still experiencing a weak or
sluggish flush after this point, it is recommended you replace the entire
Lower Supply group.
Step 5. Check the following:
1. water line pressure (20-125psi)
2. obstruction in the bowl trapway
3. obstruction in the drain
4. proper drain ventilation
Consult a professional for recommendations if any of these conditions
exist. If the drain and drain vent are clear, and the flush has not been
improved, replace the Lower Supply Assembly.

TROUBLESHOOTING___________________________________________________________________________
CONDITION: No Flush Step 1. Check the water pressure (20 psi to 125 psi).
Step 2.Check the Air Inducer for sufficient air draw. Refer to Step 2of “Weak or
Sluggish Flush.”
Step 3. Review all of Step 3 and Step 4 covered in “Weak or Sluggish
Flush” Condition.
Step 4. Replace the Flush Valve Cartridge. NEVER use lubricant on the “O”
Ring (Arrow - Figure 6).
REPLACEMENT PROCEDURE FOR LOWER SUPPLY:
Step 1. Turn the water supply off. Flush the fixture to relieve pressure in the vessel and
disconnect the water supply from the shank.
Step 2. Remove the China Tank from the China Bowl by removing the nuts/washers or
wings nuts from the bottom of the China Tank.
Step 3. Unscrew the plastic locknut that holds the shank to the bottom of the China tank
and remove the tank to bowl gasket.
Step 4. Unscrew the plastic nut that holds the vessel to the bottom of the China Tank and
carefully remove the entire vessel from the China Tank.
Step 5. Remove the Lower Supply Assembly by pulling in a downward motion. WHEN REMOVING OR REPLACING THE LOWER
SUPPLY, DO NOT WIGGLE THE LOWER SUPPLY FROM SIDE TO SIDE AS YOU MAY BREAK THE POST THAT THE LOWER
SUPPLY SLIDES ONTO. THIS IS A PRESS FIT AND ONLY MINIMUM DOWNWARD OR UPWARD FORCE IS REQUIRED. DO NOT
PROCEED TO STEP 6 UNTIL STEP 5 IS COMPLETE.
Step 6. Cut the hose just above the barbed fitting (about (1/4” above clamp) on the Lower Supply. Discard old Lower Supply.
Step 7. Insert the new Lower Supply into hose and secure with new Hose Clamp.
Step 8. Push the new Lower Supply onto the post using an upward motion.
Step 9. Reassemble vessel to China tank, tighten securely, reconnect water supply and check for leaks.
